The Need for Process Design

For every product or service process that is designed, there are dozens or hundreds of supporting processes.

How many of those are intentionally designed?

How many processes have a mechanism for feedback and continuous improvement?

Our goal is to introduce you to a technique for process modeling called discrete event simulation.

As product and process offerings becoming increasingly complex and segmented, having a tool to understand the dynamic interactions within a process is critical.

At the mean this process looks like it should be okay, but is it?

Dynamic modeling can predict the performance of this process.

Discrete Event Simulation – Inputs and Outputs

1 2 43 5

DEFINE YOUR DEMAND:• Takt time = interarrival time• Distribution of arrivals• Changing distribution and parameters

over time• Changing mix of items

DEFINE YOUR PROCESS:• Task time distribution

• By item• Capacity• Flow• Resources, shifts, skills

OBSERVE YOUR:• Queue time and variation• Utilization• Cycle Time• Lead Time• Throughput• Blocking and bottlenecks

Processes are dynamic, and the events within those processes are all interconnected. Increasing complexity of service and product offerings demand dynamic tools to help us:

• Meet customer expectations by…• The proper application of resources
